Abstract
The present report describes a stress analysis of face gear tooth. Distributed load estimated by geometrical mismatch, one of information included in Tooth Flank Film Element, operates on face gear tooth. This element, a phantom element absent from thickness, can include various particular information on a tooth flank. In this report, stress analysis in the case that misalignment and/or tooth flank modification have been given to a cylindrical gear is tried, then the interesting change of distribution of maximum principal stress can be confirmed.
